The invention is exemplified in connection with a. circular knittingmachine of the vertical type, comprising a air of cylindrical membersarranged for re ative rotation. In the present instance, there isprovided a stationary needle cylinder `20 and a rotatable cylinder 21etendino about the same and operatively connecteff to a driving shaft 22through the medium of a tooth rack 23 on the cylinder 21 and a crown 24on the shaft lUO certain of the needles in the present instance havingshort butts 28a and others having long butts 28". The needles 28 aremounted for vertical movement, in the usual manner, in grooves 29 in thecylinder 2O and, in the present instance, arek formed adjacent the facethereof with outwardly extending lugs 30. About the lug 30 on eachneedle there extend the two arms 30a of the bifurcated end ofaneedle-supporting and shifting lever 31. This lever is mounted in aslot 32 in an annulus 33 in the cylinder 2O and is pivotally supportedupon a rod 34 extending across the slot'. The usual sinkers, such asthose shown at 39 are provided between the needles.

On the cylinder 21 are carried certain cams operative upon the needlebutts 28 for imparting certain actuations to the needles, and in thepresent exempliication, these cams are shown for the sake of convenienceas arranged to cause a needle movement of the general type exemplifiedin my Patent No. 1,541,230, whereby there may be provided a multi-colorfabric, such as exem lified in my said patent as well as in my atentsNos. 1,426,576 and 1,541,230 and in my application Serial No. 37,076,tiled June 15, 1925, wherein onejyarn is formed into a series ofinterknitted loops in one section of the fabric, and a second yarn isformed into a series of interknitted loops in another section of thefabric, the yarn not entering into the fabric in any section beinginterlocked with the interknitted loops by being caught between theloops in certain, preferably alternate, wales, and being extended behindthe interknitted loops in adjacent wales. To this end, as will be seenby reference to Figs. 1 and 6, there` is provided on the cylinder 21 inadvance of each yarn feed in the direction of movement of the cylinder acam 35 arranged to cooperate with the needle butts to move all theneedles to a partially advanced yarnreceiv ing positionA wherein apreviously received yarn, such as'the yarn 36 shown in Fig. 6 1s stillretained bythe needle latches. Following the cam 35 but positionedoutwardly from the same is' a pattern-control drum 37 (hereinafter to bedescribed) forming a part f the pattern control mechanism arranged 1nthe present .instance to causeI ag further act vence of certain needlesthrough the medium of the lever 31 so as to cast oft previously receivedyarn from the latches. A thin cam 38 adapted to retract from yarnreceiving position those long butt needles not actuated by thepattern-control mechanism follows theY drum 37. Thus, in the presentinstance, needles actuated in response to the operation of thepattern-control mechanism are in an advanced position to receive theyarn (such as shown at 40) from the yarn feed for interknitting the samewith the yarn 36; the remainingv short butt needles are in anintermediate position to receive the yarn 40 for interlocking with theyknitted yarn 36 retained thereby, and the remaining long butt needlesare in a retracted position wherein they will not receive the yarn 40.Followin each of the .yarn feeds 27 and 27a on the cylinder 21 is a cam42 arranged to retract all' the advanced needles so that they mayperform the desired knitting or interlocking operations. Y

In the exemplified apparaus each of the drums 37 is provided with anaxial shaft 43 which is rotatablylmounted inA bearings 43 supported inbrackets 43b on. the cylinder 21, and is arranged for Yindependentrotation in responseto the relative rotation of the cylinders by meansof a peripheral gear 43c meshing with a stationary circumferentialtoothed rack 44 .extending about the cylinder 20 beneath the drum. Witha view to providing for the actuation of the needle shifting levers 31,each vdrum 37 carries about its periphery a` plurality of adjustableelements or plungers 45 arranged for sliding movement in a plurality ofoblique slots 46, the ends of which are adapted to receive the bentouter there isk formed a sloping bearing surface 51 adapted to'cooperate with the bearingsur- .face 52 on the outer endrof the plunger45 so that upon a movement of the member 50 toward the axis of the drumthe plunger 45 associated therewith will be thrust inwardly (toward theneedle cylinder 20). For the purpose of actuating the radial members 50of each drum at least once during each revo-v lution of the cylinder21,there are provided a number of plungers 53 each supported in ahorizontal slot 54 in a stationary table 55, and each arranged forsliding movement to a position wherein a radial memberfO onV the drumwill be pressed upon the top of the'inner end 57 ofI the plunger as thedrum 'moves past vthe same. t will be observedl that in the presentinstance the adjustable elements or plungers 45 are in suchl an obliqueposition that the inner ends thereof are behind the outer ends,"`

occurred before the plunger reaches the propl er position for impartingactuation to the member, such as a needle lever 31, to `which theactuation is to be imparted. v

With a view to controlling the operation of the plungers 53, there isprovided a patterndetermining element, which is exemplified by anendless perforated tape 58 mounted on a cylinder 59, andcooperatingmechanism exemplified by a rowy of slidable plungers 60vextending into the slots 54 and formed at their outer ends with fingers61 arranged for insertion in perforations of the tape 58 when suchlperforations are aligned therewith. Onthe inner end of the plunger 60is a lug 62 extending downwardly along the inner side of an upwardlyextending lug 63 on the plunger 53, these lugs being normallyAheldpadjac'ent one another by a spring ,64 arranged to press againstopposed shoulders 65 and 66 of the plungers 53 and 60, respectively.

The particular pattern band58 exemplified p is perforated to form aseries of longitudinal rows of pattern control configurations and 1sarrangedfor step by `step movement upon the cylinder 59, in a mannerhereinafter to be described, whereby said with the row of. fingers 61 asdesired.l The cylinder 59 is mounted at one end in gear box 6'8 and atthe other on an arm 69 supported on P the table 55. For the purpose ofpermitting the replacement of a tape 58 by a tape haying differentpattern controlling configurations, the arm 69 is removably secured uponthe cylinder 59 and is rotatably mounted at 0 to the stationary table55. A handle 71 is provided thereon to facilitate the operation thereof.

In order to permit the step by step movement of the tape 58, there isprovided means for withdrawing the fingers 61 inwardly from the tape. Inthe present instance, this means comprises upwardly plungers by acarrier 74 attached to the cylinder 21 and so positioned as to followeach drum inthe direction of lmovement of the cylinder. This cam isarranged to bear on the outer edge o the lugs 72 to cause inwardmovement of the plungers 53 and the finger-carrying plungers 60 a Forthe purpose-of causing the proper positioning of the -plungers 53 withrespect to a particular pattern controlling configuration on theperforated tape, there is provided in the exemplified apparatus a cam 75carried by the annulus 74 in a position in. advance of the drum in thedirect-ionof movement of the cylinder and adapted to bear against theinner .edge of the lugs 72 `to thrust the rows may be aligned.

extending lugs 72 on the P 53 and Acooperating cams 73 carried P plunger53 to remain in an outward position but, when there is no perforation inthe portion of the tape aligned with a particular finger 61, thespring64l is retained in a compressed position so that, when the bearingsurface of the cam 7 5 recedes, the compression of the spring vwillpress the plunger 53 inwardly to a, position wherein it will beoperative to cause actuation of the sliding members 50 and a resultantinward movement of the plungers 45 on the drum.

As will be apparent from the foregoing exemplilication, a wide varietyof fabrics may be produced in accordance with the invention,by theemployment of pattern bands having various types of configurations.Among the various types'of cloth which may be produced upon a machineembodying the resent invention are fabrics embodying an interlock stitchsuch as disclosed in my prior Patents Nos. 1,426,572 and 1,541,230. Forexample, in the production of such a fabric upon a machine having twoyarn feeds and equipped at each feed with cams and drums such as themembers 35, 37, 38 and 40, the pattern band may be formed so that theerforations on each pattern row appear only adjacent those fingers 61with which a perforation in the preceding pattern row was not aligned.For example, assuming that the machine has finished an operation whereinone or more pattern rows withoutl perforations have been usedto producea lJersey stitch, ywherein each of the needles have knitted so that theposition of the last yarn received `is represented by the yarn 36 1nband will be formed with perforations at the oints indicated' in Fig. 6,so that certain luralities of adjacent needles and certain individualneedles will not be actuated prior to the passage of the yarn feed 27,and the cam 38 will be operative on such of these f needles as have longbutts. The nextk pattern to set the fingers 61 row, which is operativethe adjustable elefor the adjustment of ments on the drum preceding theyarn feed 27 a, will be perforated at those points where there were noperforations in the preceding pattern row and will have no perforationsat those points where the preceding pattern row was perforated, so thatall of the needles which Were advanced for knitting the yarn from theyarn feed 27 will not be actuated, and will have vbeen yseparated by thecam 38 preceding the yarn feed 27, so as to be in interlocking positionat the time of the passage of the yarn feed; and so that those needleswhich lwere in interlocking nosition at the time of vthe passage of theyarn feed 27, and which consequently did not knit the yarn 40, will havebeen actuated so as to be in knitting position at the time ofthepassageof the yarn feed 27. If .further information with respect to knittingoperations of this general type is desired, reference may be had to mysaidvPatent No. 1,541,230. It is to be understood, ,of course, that theinvention is in no wise limited to the use in Connection with theproduction of an interlock fabric or of any other particular type offabric, but may be used inthe production of any wide variety of types offabric. If the machine is to be used to produce a fabric wherein thepattern effects vary from row to row, in the knitting, the perforatlonsor other pattern control configurations may appear atvany such points onthe pattern control member as will cause the proper needle actuationsfor that purpose. As will be apparent,-`the invention makes possible thevariation of patterns from row to row and from Wale to Wale of afabricaccording to any predetermined design and` accomplishes thisresult in a ready and faclle manner.

Moreover, the invention may be employedf to form as exceedingly finelyknit fabric containing .varied pattern-effects, since mechanism such asexemplified is readily adapted for use in the actuation of needlesspaced as closely as twenty-seven 0r more to the inch. In practice, itis ordinarily desirable to perform the knitting operations with a row ofneedles extending entirely around the needle cylinder, and it will beevident from the above that once the plungers on the drum are adjusted,pattern control actuations will not only be imparted to certain needlesof the group corresponding to the plungers 53', but also to similarlyplaced needles in succeeding groups about the cylinder20. In order,however, to realign the plungers 45 on each drum after a revolution ofthe drum` about the cylinder 20, eachof these plungers is formed, in thepresent instance, with a radial butt 80, and associated withk each drumthere is provided an aligning cam 81 mounted for revolution but not forrotation with the drum, and movable into position for aligning the butts80 prior to the passage of the drum over the plungers 53. As exeemplifed, each cam 81 is carried onl the end of a lever 82 standingupwardly from a shaft 83 rotatably mounted on the cylinder 21 in aposition inl advance of the drum in the direction of movement of thecylinder. Attached to they, shaft 83 and extending outwardly therefromis an actuating lever 84 having on-the outer end thereof a member 85formed with upper and lower cam surfaces, In order to causev the cams 81to be moved into punger-aligning position at the desired time in theoperation of the machine, there is provided a pin 86 mounted on thestationary table adjacent the first plunger 53 in the directionofmovement of the cylinder 21 in such position that, when the cam 81 isin inoperative position, the pin will bein the path of the upper camsurface of the member 85, to cause an outward movement of the cam 81 toplunger aligning position. f f f With a view to permitting the plungers45 to remain throughout the remainder of the revolution of the drum, intheposition in which they have been set by the tape conf trolledplungers so as to cause succeeding groups ofthe .needles throughout derto be actuated in the same manner as the group of needles actuateddirectly in response to the position of the plungers 53, there isprovided on the stationary table 55 adjacent the last plun er 53k in thedirection of the cylinder 21 are easing pin-87 adapted to cooperate,when the cam 81 is in operative position with the lower cam4 surfaceofthe member 85to cause downward movement of the lever 84 and an inwardmovement of the cam 81. y V j In order toA prevent the displacement ofthe lever 84 from the position in which it has beenset'by the pins 86and 87, the lever is provided with lower and upper notches 88 and 88aand there is mounted on a bracket 89 extending upwardly adjacent thelevel-'84 from the cylinder be thrust intov an aligned notch by a spring89h.

while fhemeehe'niemiebeve exemplified ie.

well adapted for use invaccordance with 'the invention, it will beappreciated that variousV other types yof movement-imparting members maybe employed without departing from the spirit and ample, instead ofmembers suchvas plungers 45 other types of adjustable elements may beemployedin the pattern drums. An example of` mechanism employing onesuch alternate type of adjustable elements is shown in Fig.

A drum 90, which, as exemplified, is similarly mounted and is generallysimilar in form to the drum 37, is formed with a plurality of axialslots 91 in which there are mounted a plurality of levers 92. The innerends 93 of these levers are adapted to press against the outer ends 94of needle Shifters 95, which may be similar in all'respects to theneedle Shifters end thereof is not the drum are'notoblique. Eachadjustable lever 92 is pivoted on a rod 96 extending across the leverslot 91 and is provided with a radial extension 97 so formed that whenthe inner end 93 of the adjustable lever is in a position above thenormal position of the shifting lever 95, the extension 97 will projectdownwardly a sufficient distance so that it will contact with a lever53, such as described the cylin-.

31 except that the outer bent, since the slots on 21, a kball 8,9aarranged to scope of the invention. For'exabove, when the latter is inan inward position so that the extension 97 will be forced upwardly tocause a pivotal movement of the adjustable lever 92 and an operativeshifting of the shifter, 95.

For the purpose of maintaining the adjustable lever 92 in position forexerting downward pressure on the inner end of a successive shifter 95to impart an actuation to needles in a successive group, each lever 92is provided with an outwardly extending projection 98 operativelyassociated with which is a locking member 100 having 'formed thereon adog 101. Each locking member is pivotally mounted in a slot 102 on thedrum and is pivoted on a rod 103 extending across the same in suchmanner that when the downward extension 97 of the lever 92 isforced-upwardly by being brought into contact with a plunger 53, theprojection 98 will catch on the dog 101 and be maintained in suchposition. In order to release the projection 98 from the dog 101 afterthe drum has completed each cycle of revolution, there may be providedsuitable tripping means, such as outwardly extending projections 104 onthe pivoted locking members and a cooperating tripping cam 105 whoseoperations may be controlled by mechanism similar to that employed foroperating the cam 81.

The locking member 100 is normally retained in operative position bymeans of a spring 106 fastened to the locking member at. 106a andbearing against a surface 106b provided by a portion of the frame of thedrum.

As will be apparent, the pattern-controlling actuations imparted to theneedles may be such as to cause a vertical movement of vertical latchedtype needles, such as those described above, or to cause any other typeof needle actuation.

There is shown in Fig. 10, for example, a type of mechanism adapted toimpart pattern-controlling actuations to the beards of spring beardneedles. This mechanism is exemplified in connection with a machine.

containing the usual cams for advancing and retracting needles, a seriesof sinkers 107 and pattern controlling mechanism of the same generaltype as that exemplified in Figs. 1 to 6 inclusive. The needles, asexemplified at 108 are provided in the usual manner with butts such asshown at 109 intermediate their ends but, instead of being latched, theyare of the spring. beard type with the hook thereof extended to form aspring beard 110, the point of which is adapted to be closed to permityarn already received, (such as shown at 111) to be passed over the sameupon the retraction of the needles. When 'the beard is not pressedclosed on the other hand, the yarn previously received will ride upon.the shank of the needle and will enter the beard along with the yarn(such as the yarn 112) received from a yarn feed.

Accordingly, there is provided in the present instance a shifting lever,113, substantially similar to the shifting lever 31. Extending betweenthe bifurcated ends 114 of this lever is a lug 115 extending outwardlyfrom a beard pressing plunger 116 slidably mounted in a slot 117 alignedwith the needle slot and formed in an annulus 118 attached to the needlecylinder., On the upper end of the plunger 116 is a cam member 119 a1'-ranged to press against the beard 110 of the needle when the presser israised and the needle is lowered from yarn-receiving position, but n otto press against the same when the presser is not raised.

Accordingly, when a particular adjustable element (such for example asplunger 45) on the drum isin an inward position, the lever 113 will beactuated and the presser 116 raised to operative position wherein itwill press beard 110 inwardly to cause the needle to cast the previouslyreceived yarn, whereas if the plunger 45 is in an outward position, .thelever 113 will not be actuated to raise the presser and the latter willremain in a position wherein it will not be adjacent the bulge 150 onthe beard, and the group of the previously received yarn will slip intothe hook of the needle.

Various modifications of the above mechanism are of course permissible.For example, it will be apparent that mechanism of the general typedescribed may be used in the actuation of pressers mounted in any of avariety of Ways, as by being pivotally mounted. (See the patent toHowie, No. 1,407,684.)

It will moreover be apparent that mechanism embodying the invention maybe employed to actuate yarn-manipulating mechanism other than needles orneedle beards. For example, such mechanism may be used in the actuationof the sinkers so as to control the tightness of the knit by a movementof the sinkers such as disclosed in my copending application, Serial No.37,076, filed June 15, 1925. It will be obvious that the use ofmechanism. such as above described, would permit the actuation of thesinkers so as to vary the tightness of the knit from row to row and fromWale to Wale.

`The invention, moreover, is in no wise limited to the use of a seriesof vertical needles, but is well adapted for employment with varioustypes of needle arrangements. An exemplification of one such otherarrangement is shown in Figs. 12 to 14, wherein the pattern controlmechanism, such for example as that shown in Figs. 1 to 9 inclusive, maybe employed to impart pattern determining actuations to a series of dialneedles on a circular machine of the composite type. The machine may beof any 'usual form, but in position the latter order to providesufficient room for the arrangement of the mechanism for actuating thedial needles, it is ordinarily desirable to with their hooked endspointing inwardly.

The exemplified machine includes a pair of supporting members and 126fragmentary sections of which are shown in Fig. 12 arranged for relativerotative movement, the member 125 serving as a needle carrier, and themember 126 serving to support the needle actuating mechanism. Preferablythe needle carrying member 125 is stationarily mounted and the member126 rotatably mounted. In the present instance there are formed on aninner cylindrical surface provided on the member 125, a plurality of acircular row of vertical needles 128 are mounted for longitudinalmovement in response to needle actuating mechanism of any suitable typecarried by the member 126. This mechanism comprises a complete set ofneedle actuating cams or other cam 129 being illustrated. An annulus 131which in the present instance is also stationarily mounted, is formedwith a plurality of radial grooves 130 in the inner end of which aseries of dial needles 132 are mounted forV inward and outwardhorizontal movement to perform knitting operations 1n conjunction withthe vertical needles 128 in such manner as will be readily apparent tothose skilled in the art. In the outer end of the slots 130 are aplurality of plungers 133, each arranged or sliding movement to impartactuations to one of the needles 132. Each of plungers 133, asexemplified, is also arranged for pivotal movement upon a nub 134extending upwardly from the inner end therof, and is normally held in araised position by a spring 135 which is mounted in annulus 131 andarranged to thrust a knob 136 against the lower surface of the plunger.Positioned directly above the plungers 133 is an annulus 137 arranged torotate' in unison with the rotatable member 126 and attached to the mainbody thereof by means of a series of brackets 139. In the lower surfaceof the annulus 137 is an annular groove 140, into which a plurality ofbutts 141 formed on the plungers 133 are adapted to extend when theplungers are in a raised position. Mounted on the annulus 137 andextending therefrom into the groove 140 is a cam member 142, arranged tobear upon the butts 141 when the plungers 133 are raised, so as tothrust the plungers inwardly and to cause an inward movement of theneedles 132. The cam 142 is so positioned, however, that when theplungers 133 rest upon the bottom of the slot 130, the cams will passover the butts 141 without actuating the plungers. Accordingly, theremay be' provided suitable patterncontrol mechanism operative upon theupper ends of the plungers 133 for selectively pressing the plungersdownwardly toward the slots 127, in which members, only the bottom ofthe groove 130, and to this end there is employed, in the presentinstance, a drum 143, similar to the drum 37 shown in Fig. 2, andcarrying independently adjustable elements 145 which may be similar tothe plungers 45 on the drum 37, and which are arranged for selectiveadjustment to positions wherein they will bear upon the outer end of theplungers 133'upon the rotation of the drum. The drum 143 may be mountedon the rotatable annulus 137 for independent rotation in response to themovement thereof,

and may have associated therewith a suitable pattern-determining elementand suitable pattern-control mechanism supported on a stationary tableand arranged in a manner similar respectively to the pattern band 58 andthe pattern-control mechanism shown in Figs. 1 to 9 inclusive. Theneedles 132, as exemplified, are formed with upwardlyextending butts inthe usual manner, and there may be provided suitable cooperatingmechanism carried by the annulus 137 and including a restoring cam, ofany well known type, for restoring the needles 132 and the plungers 133to their original positions.

n certain instances, it is desirable that each group of needles repeat acertain type of knitting operation for incorporating a particularpattern into the fabric throughout a number of rows before a variationin the pattern occurs. This result may be obtained, of course byrepeating on successive rows of the pattern-determining element thepattern-control configurations on lprevious rows thereof, brit such anarrangement limits the variety of configurations that can be formed on apattern band of a given length. To avoid this difliculty, there may beprovided mcans whereby the perforated tape or other pattern-determiningmeans may be shifted one step at each cycle of the operation of themachine or may be retained in p0- sition throughout several cycles, inaccordance with the operation of setting mechanism connected therewith.

ne form of such means is exemplified in Figs. 15, 16, 17 and 18.

In the present exemplification, the tapecarrying cylinder 59 has asquareend 210 projecting into a close fitting cavity of a sleeve 211 which isrotatably secured within a collar 212l forming a portion of the gear box68. The further end of the sleeve (with reference to the tape cylinder59), provides a driven clutch member 213 adapted to cooperate with thedriving clutch member 214 on a sleeve 215 slidably and rotatably mountedon a shaft 216 extending into the sleeve 211. In the presentexemplification, the clutch member 213 is formed with a plurality ofindentations 217, and the clutch member 214 is formed with a pluralityof projections 218 arranged to fit into said indentations. The sleeve215, as exemplified,

llO

222. The sleeve 215 is aflixed to a sleeve 225 by pins 226 and bothsleeves are mounted for rotation upon the shaft 216. Loosely keyed tosleeve 215 by means of a plurality of keys 223 in keyways 224 is ixedlymounted on the sleeve 225 the driven' member 227 of a Geneva movement,the driven member 227,

in the present instance, being formed. with six locking surfaces 228 andsix driving slots 229. On a shaft 230 extending across the gear box andmounted thereon are secured the locking disc 231 and the driving member232 of the Geneva movement. The locking disc 231 is so formed that thecircumference will it into an adjacent locking surface 228 vof themember 227 during livesixths of the revolution of the disc, but isrecessed, as shown at 233, to permit the rotative movement of the member227 during the remaining one-sixth of its revolution. To cause suchmovement there`is provided a pin 234 carried by the driving member 232in a position adjacent the recess in the member 231 and adapted to litinto a slot 229 to move the driven member 227 one-sixth of a revolution.The shaft 230 is operatively connected through the medium of a pair ofgears 235 and 236 to a shaft 237, which, in turn, is operativelyconnected to a drive shaft 224a by a further pair of gears 238, 239(Fig. 1). On the drive shaft 224 is a gear 225 meshing with the toothrack 23. In the present exemplication, wherein two yarn feeds areemployed, the gearing is arranged to cause two rotations of the shaft230 to each rotation of the cylinder 21 so that a stepping movement ofthe pattern band 58 may be caused (when the clutch-members 213, 214 arein engagement) prior to the passage of each drum (such as shown at 37)over the actuating members exemplified by the plungers 53.

As set forth above, there is preferably employedsuitable mechanism forwithdrawing the clutchfmember 214 from engagement with the clutch-member213 at predetermined intervals in the operation of the machine, and tothis end, there is provided, in the present exemplification, a lever 241lpivotally mounted on shaft 242, which, in turn, is supported onarms-243, 244 extending outwardly beyond the gear-box 68. One sectionarm 245 ofthe lever 241 extends downwardly from theshaft 242 and isformed with a bifurcated end 246, the divisions of which are securedabout a pin 247 which extends through a hole in the shaft 216 and isrotatable therein. The other section 248 of the lever extends outwardlyfrom the gear-box and is formed at its outer end with a down- Wardlyextending arm 249. The lever is normally held with the end 246 thereofadjacent the gear-box, so as to permit the clutchmembers 213, 214 toremain in mesh, by means of a coil-spring 250. Directly beneath the arm249 of the lever is a sprocket-wheel 251 attached to a sleeve 252extending about the shaft 230 and carrying, in the present in` stance,an endless chain 253. With a view to causing the projection 249 on thelever 241 to be raised so as to carry the end 246 of the lever and theshaft 216 in a direction away from the cylinder 59 so as to cause theclutch-members 213, 214 to be disengaged at certain periods in theoperation of the machine, certain links in the chain 253 are formed withprojecting cam-members 254 arranged for operative engagement with theprojection 249. In order to cause the rotation of the sprocket-wheel 251and a consequent movement of the chainI 253 thereon, the sleeve 252 maybe ixedly secured to the shaft 230, but in order to secure a greatervariety of design in the fabric produced by the machine without theemployment of a chain of undue length, there may be employed suitablemechanism for causing a movement of the chain or other lever-actuatingmember during only certain portions `of the movement of the shaft 230.To this end, there is provided in the present exemplification a ratchetwheel 255 attached to the sleeve 252 and a larger lratchet wheel 256loosely mounted on the sleeve 252 in a position adj acent the wheel 255.A pawl 237 of sufficient width to extend across both wheels is mountedon a member 258 formed with a counter-weight 259 and mounted on, aneccentric disc 261 formed on the end of the shaft 260. In order furtherto limit the' extent of movement of the chain with respect to themovement of the machine, the larger wheel is so formed, in the presentinstance that only the notches between every fourth tooth will be ofsuiiicient depth to permit the pawl to be operative upon a tooth of thewheel 255 to turn the same so as to cause the chain to be moved one linkby the sprocket wheel. In the present exemplitication the gearing isarranged to cause four revolutions of the shaft 237 to each revolutionof the cylinder 21. Other arrangements may of course be employed. Inorder to prevent accidental shifting movements of the cylinder 59 whentheclutch-members 213 and 214 are out of engagement, there may beprovided suitable means, such as the six knobs 266. (as shown Y in Fig.18) formed on the periphery of the clutch-member 213 and a cooperatingspring 262. arranged to releasably enga-ge the knobs. While a machineembodying two yarn feeds and two drums has been exemplified, it will beunderstood that any further number of yarn carriers and correspondingpattern-control mechanisms may be employed. lt will be appreciated,however, that the space between successive drums, such as the drums 37,should ordinarily be suiciently greater than the space occupiedk by theactuating-members, such as exemplified by the plungers 53, thel patternband, if desired, between the operation of the actuating-members uponsuccessive drums. However, if such resetting is not desired betweencertain successive drums these drums may be arranged close together foractuation in response to a single position of the,congurations presentedby the pattern band. Furthermore, in certain cases certain of the drumsmay be omitted and an ordinary pattern wheel or other suitable mechanismemployed at certain of the varn feeds. It is to be understood, moreover.that while there are employed in the exemplilied machine, elements fortransmitting movement of the plungers to the needles, the invention inits broader aspects is capable of embodiment in machines so constructedthat the adjustable elements on the drum or other rotating memberactuate the needles directly.

.It will be appreciated that the invention notv only contemplatesimparting selective actuations both to a row of latched needles (bycausing longitudinal movement of certain oi the needles) and to a row.of spring needles (by causing the beardsy of certain needles to beclosed) whether the needles actuated are the vertical or dial type orboth; but in its broader aspects, it is adapted successfully to beembodied in connection with any of a widel variety of types of machines.

The term cylindrical member as used in the appended claims is intendedto refer to either of a pair of members (one rotatable and the otherstatignary), employed in a circular knitting machine, t-he one tosupport the needles, the sinkers, and the Inembers directly associatedwith the needles, and the other to support the needle actuating meansmounted for movement with respect thereto, regardless of the generalform of the supporting members or whether' they are employed to supportvertical cylinder needles, dial needles, or both, on the one hand; or,on the other, mechanism for causing the actuation of any of theseneedles.

Since certain changes may be made in the above construction anddifferent embodiments of the invention could be made withoutl departingfrom the scope thereof, it is intended that all matter contained in theabove description or shown in the accompanying drawing shall beinterpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended tocover all of the generic and specific features of the invention hereindescribed, and all statements so as to permit the resetting of o t thescope of the invention which as a matter of language might be said tofall therebetween.
